Real-time emotion recognition and interaction design of visual art images on mobile terminals based on deep learning

Di Chen, Jun Shi

Emotion recognition in visual artworks remains challenging because artistic images often contain abstract form, stylistic variation, and distorted visual representations that differ significantly from natural images. Existing deep learning models frequently struggle to generalize across artistic styles and accurately capture emotion-related cues; …

Microphase‐Separated Liquid Crystal Elastomer Actuators With Exceptional Strength and Toughness

Luping Lu, Xiaorui Zhou, Yi Sheng, Ben He et autres

ABSTRACT Liquid crystal elastomers (LCEs) have emerged as attractive soft actuators capable of undergoing large and reversible actuation. Their potential for practical applications, however, has been fundamentally constrained by an intrinsic trade‐off: the chain flexibility required for reversible actuation inherently restricts molecular …

4D printing of trigger-free shape-memory hydrogels towards self-adaptive substrates for bioelectronics

Chujun Ni, Chunlei Zhang, Zhenwei Qin, Ke Qiao et autres

Shape-changing smart substrates are revolutionizing implantable bioelectronics by offering minimal invasiveness and self-adaptive geometric conformity. However, precise manipulation of shapeshifting, which is critical for the successful implantation, are hindered by triggering accessibility and cumbersome customization. Here we introduce a digital 4D printing …

Circular 3D printing of high-performance photopolymers through dissociative network design

Tiantian Ni, Jingjun Wu, Zizheng Fang, Kexuan Yang et autres

One approach for closed-loop plastics recycling relies on reverting polymers back into monomers because one can then make new plastics without loss of properties. This depolymerization requirement restricts the molecular design to making polymers with high mechanical performance. We report a three-dimensional …
